DETAILED DESCRIPTION

Embodiments of the present disclosure will now be described in detailbelow and with references to the drawings.

Referring to FIGS. 1-2, an atomizer 11 for an electronic cigaretteincludes a housing 10, a mouthpiece cover 20 at one end of the housing10. The mouthpiece cover 20 defines an air outlet 201. Then referring toFIGS. 3 and 5, an atomizing part 60 for atomizing tobacco solution and asolution cup 31 are disposed in the housing 10. The solution cup 31defines a solution reservoir 30 for reserving the tobacco solution. Theatomizing part 60 includes an atomizing cup 62 with an atomizing cavity621, and an atomizing unit 61 arranged in the atomizing cavity 621. Thehousing 10 defines an air inlet 202, an aerosol outlet 102, and an airpassage 101 communicating with the air inlet 202 and the aerosol outlet102. The mouthpiece cover 20 is arranged at one end of the housing 10with the aerosol outlet 102. The air outlet 201 communicates with theaerosol outlet 102. A first solution conducting component 40 is arrangedbetween the solution reservoir 30 and the atomizing part 60. Theatomizing part 60 is configured for conducting the tobacco solution fromthe solution reservoir 30 to the atomizing cup 62, and is capable ofpreventing the tobacco solution from leaking out. In the presentembodiment, the first solution conducting component 40 is a porousceramic body. The first solution conducting component 40 absorbs thetobacco solution stored in the solution reservoir 30 by capillaryaction, holds the tobacco solution, and prevents the tobacco solutionfrom leaking out. After the tobacco solution permeates the firstsolution conducting component 40, the tobacco solution is stored in thefirst solution conducting component 40, and is then provided to theatomizing unit 61 for atomization. In the present embodiment, thesolution cup 31 is substantially cylindrical, the air passage 101 is agap formed between the solution cup 31 and the housing 10, and the firstsolution conducting component 40 is plate shaped.

Because the first solution conducting component 40 is arranged betweenthe solution reservoir 30 and the atomizing part 60, and the firstsolution conducting component 40 is made of porous ceramic, the firstsolution conducting component 40 can convey the tobacco solution fromthe solution reservoir 30 to the atomizing cup 62 for atomization by thecapillary action due to porous characteristics. The first solutionconducting component 40 can prevent the tobacco solution in the solutionreservoir 30 from leaking out. Thus, the first solution conductingcomponent 40 conducts the tobacco solution well, and has the effect ofpreventing the tobacco solution from leaking out. Furthermore, thepresent atomizer 11 has the advantage of simple assembly.

Referring to FIG. 3, a connecting tube 50 for fixing the solution cup 31is fixed in the housing 10. The atomizing part 60 is received in theconnecting tube 50. Also referring to FIG. 4, the solution reservoir 30includes an opening end 301. The first solution conducting component 40is disposed in the opening end 301, and abuts against one end of theatomizing cup 62 with the atomizing cavity.

A first electrode 70 and a second electrode 90, which are configured forconnecting to an external power source 12 (referring to FIG. 9), arefurther arranged in the housing 10. An insulator 80 is disposed betweenthe first electrode 70 and the second electrode 80, and the insulator 80makes the first electrode 70 insulated from the second electrode 80. Inthe present embodiment, the insulator 80 is an insulated ring nestingthe second electrode 90, and is made of silica gel. The insulator 80makes the first electrode 70 not in contact with the second electrode90. Referring to FIG. 5, the atomizing unit 61 includes a heating wire612 and a second solution conducting component 611. One end of theheating wire 612 is electrically connected to the first electrode 70 ofthe atomizer 11, and the other end of the heating wire 612 iselectrically connected to the second electrode 90 of the atomizer 11.The second solution conducting component 611 is in contact with thefirst solution conducting component 40 so that the tobacco solutionreserved in the first solution conducting component 40 is conveyed tothe heating wire 612 for atomization. In the present embodiment, thefirst electrode 70 is electrically connected to a negative electrode ofthe power source 12, and the second electrode 90 is electricallyconnected to a positive electrode of the power source 12. The firstelectrode 70 includes screws for connecting with the external powersource 12, and the screws are internal screws 701. The air inlet 202 isformed in the second electrode 90.

In the present embodiment, the second solution conducting component 611is made of glass fiber, the housing 10 is made of a partiallytransparent housing, and the solution cup 31 is made of transparentmaterial. Because the quantity of the tobacco solution in the solutionreservoir 30 can be clearly seen through a transparent part of thehousing 10, it is prevented that the heating wire 612 keeps heatingafter the tobacco solution is used up. In other embodiments, the secondsolution conducting component 611 may also be made of porous ceramic,and the entire solution cup 31 and the entire housing 10 may be made oftransparent material.

Referring to FIGS. 6-8, the present embodiment mainly differentiates thefirst embodiment in that: an housing 10′ and the solution cup 31 of thefirst embodiment are integrally formed; a solution reservoir 30′ has anannular structure, defines an air passage 101′ centrally located withinthe solution reservoir 30′, and the air passage 101′ functions similarlyas the air passage 101; a first solution conducting component 40′includes a porous ceramic body 402 and a cotton cloth 404 formed on thebottom of the porous ceramic body 402. The cotton cloth can furtherprevent the tobacco solution from leaking out. In the presentembodiment, screws for connecting the external power source 12 areexternal screws 702. The housing 10′ is an entirely transparent shell.The mouthpiece cover 20′ is made of semi-transparent material.

Referring to FIG. 9, an electronic cigarette includes an atomizer 11according to the first embodiment, and a power source 12. The atomizer11 and the power source 12 are connected via screw threads. The powersource 12 is configured for supplying power for the atomizer 11. Inother embodiments, the atomizer 11 can also be replaced by the atomizer10′ as described in the second embodiment.
